如何使用 Notepad++ 删除每行的最后 13 个(或 n 个)字符 [英] How to remove the last 13 (or n) characters of every line using Notepad++

问题描述

我有一个文件，每行都以 Mar 15, 2013 和其他日期结尾，所以我需要删除每行的末尾，比如最后 13 个字符

I have a file which each line that ends with Mar 15, 2013 and other dates so I need to remove the end of each line say the last 13 characters

每行都有不同的长度和不同的字符，所以不能使用任何东西作为分隔符.

Each line is a different length and has different characters so cant use anything as delimiters.

推荐答案

您可以在 search and replace-dialog (Ctrl+H) 即锚定到行尾:

You can use a regular expression in the search and replace-dialog (Ctrl+H) that is anchored to the end of the line:

.{13}$

然后用空替换它.当然，您可以使用更具表现力的正则表达式来仅匹配特定格式的日期，而不匹配其他任何内容.

Then replace it with nothing. And of course you could use a more expressive regex to match only dates in your particular format and nothing else.
